Kawasaki disease has an unclear pathogenesis. It is speculated that it may be related to infections by microorganisms or other pathogens, familial genetic susceptibility, or autoimmune functions. Currently, the entire medical history is unclear, and there is no specific epidemiology identified for the onset of the disease; it can occur in any of the four seasons. The disease primarily affects infants and young children, with about 80% of cases occurring in children under five years of age. The ratio of male to female incidence is approximately 1.5:1. Thus, Kawasaki disease is most commonly seen in infants and young children. Currently, there is no definitive explanation for the mechanism of the disease.

Is IgE high in Kawasaki disease?

Kawasaki disease, also known as mucocutaneous lymph node syndrome, has an unclear pathogenesis. It is speculated that certain components of infectious sources, such as superantigens, can activate CD30 T cells and CD40 ligand expression directly by binding with T cell antigen receptor fragments without going through mononuclear macrophages. Under the induction of carrier cells, there is polyclonal activation and reduced apoptosis of B08 cells, resulting in the production of large amounts of immunoglobulins such as IgG, IgM, IgA, and IgE, and cytokines. Therefore, the IgE levels in Kawasaki disease are elevated.

Kawasaki disease peeling symptoms

Kawasaki disease is a disease with unclear etiology and unclear pathogenesis of the autoimmune system. Its main pathological change is systemic vasculitis, commonly occurring in the coronary arteries. At the onset, symptoms in the hands and feet include stiff swelling and erythema during the acute phase. In the recovery phase, membranous peeling occurs at the junction of the skin and the nail base of fingers and toes, and there are transverse grooves in the nails. In severe cases, the nails of the fingers and toes may also fall off. Additionally, its skin manifestations include polymorphic skin plaques and scarlet fever-like rashes, which commonly appear in the first week of the disease, with redness and peeling of the skin around the anus.

Does Kawasaki disease cause vomiting?

Kawasaki disease is a disease with no clear etiology, commonly seen in infants and toddlers, with eighty percent of cases occurring in children under five years old. Its main pathological change is systemic vasculitis. The main symptoms include fever, congested and cracked lips, diffuse congestion of the oral mucosa, swollen tongue papillae, and strawberry tongue. Other symptoms may include swelling of the hands and feet, polymorphous erythema, and enlarged lymph nodes. There could be subsequent cardiac complications, primarily affecting the coronary arteries. Kawasaki disease may cause vomiting due to the diffuse congestion in the oral cavity, and the pharynx might also be congested. When children experience significant congestion, their laryngeal reflex might be sensitive, possibly leading to vomiting. Furthermore, children with Kawasaki disease might develop secondary infections from other bacteria and viruses, which could also lead to symptoms like vomiting. Therefore, the manifestations of Kawasaki disease can vary, and if significant vomiting occurs, it should be investigated to determine the cause.

Is Kawasaki disease easy to treat?

Kawasaki disease, also known as mucocutaneous lymph node syndrome, is a self-limiting disease but is an acute systemic vasculitis commonly seen in infants and children under the age of 5. The primary clinical manifestations include non-suppurative cervical lymphadenopathy, oral mucosal lesions, conjunctival congestion, prolonged fever, polymorphous rash, and hard swelling of the hands and feet with fingertip desquamation. Cardiovascular damage is the most severe complication of Kawasaki disease and can lead to coronary artery aneurysms and coronary artery dilation. If Kawasaki disease is not treated promptly, the incidence of developing coronary artery aneurysms is 15%-25%, making Kawasaki disease one of the most common causes of acquired heart disease in infants and young children. Therefore, timely treatment of Kawasaki disease is crucial, generally involving anti-inflammatory treatment, immune support, and symptomatic management. If there is no concomitant coronary artery damage, treatment involves symptomatic management. If there is coronary artery damage, the treatment duration will be longer and regular follow-up is necessary. The course of the disease can extend over months or even years, thus treatment of Kawasaki disease needs to be tailored based on the individual's condition and clinical symptoms.
